Amongst the many advantages of sharpening tools with Japanese Water Stones is the ease with which you can re-flatten and or resurface the stones. This Professional grade Ceramic Flattening Water Stone gives the user the option of always sharpening on a flat surface, thus obtaining the very best possible results that can be achieved with Japanese Water Stones.

The hard ceramic particles and bond, means it will never wear out under normal use.

Keep one to hand and use frequently by just rubbing it with a circular motion across the top of the Japanese Water Stone you wish to flatten.

The natural wearing of the Japanese Water Stones often produce a hollowing or concave effect on the surface of the stone, however, it can easily be re-trued using a Ceramic Flattening Stone. The 150 grit Ceramic Flattening Water Stone should be used on a fairly regular basis, to dress all of your Japanese Water Stones and keep them in a pristine, absolutely flat, condition. If a Water Stone is not dressed regularly the loss of a flat working surface will become exponentially distorted, which will not only make it harder and harder to re-flatten the surface of the Water Stone, but more importantly with affect the quality of your sharpening performance. Re-truing the stone will allow very accurate honing to be achieved. The Ice Bear Ceramic Flattening Water Stone will flatten all Japanese Water Stones at an incredible rate, since the ceramic particles are harder and have a stronger bond than are use in the Water Stones, as such they will simply dislodge any grit particles that lay on the surface of the Water Stone.

The Ice Bear Ceramic Flattening Water Stone measures 155mm long by 52mm wide by 25mm high and will last almost indefinitely when use under normal use.

Water as a Lubricant and Soaking the Stones

As is usual with Japanese Water Stones they need to be saturated and the constantly doused with water if maximum performance is to be achieved whilst they are in use. To do this, simply place your Japanese Water Stones in a bucket of water and leave them there to soak for about 5 to 10 minutes before you start to use them. Then, whilst in use, Keep sprinkling the surface of the stone with clean water and or when it becomes dry. It is important to note, however, that you should never leave Japanese Water Stones in water if there is the remotest chance that the water they are in will freeze, since there is a strong possibility that this may crack your stone.

Using Japanese Combination Water Stones
(The 5-Phase Basic Principles to Achieving a Razor Sharp Cutting Edge)

Phase One to achieving a truly Razor Sharp Cutting Edge, if your knife blade has become excessively dull, damaged or chipped, is to re-establish a proper cutting edge and remove all of the damage. To do this efficiently and in minimal time you should use the 240 grit (Extra-Course) Japanese Water Stone or a good quality Extra-Course Diamond Whetstone.

This 240 grit (Extra-Course) Japanese Water Stone cuts steel with amazing speed, but as is the nature of these stones they wear somewhat quicker than would an oilstone so when these fast cutting stones eventually do become hollowed, or concave, in the use, they can easily be re-trued using the Ceramic Flattening Stone. This massive Water Stone measures 205mm long by 75mm wide by 50mm high so this massive lump of stone is going to last a long time.

Phase Two is to use the 400 grit and then the 800 grit Japanese Water Stones. These two Course water stones are used to flatten the backs of blades and form the cutting edge; they leave the metal dull but smooth.

Phase Three to achieving a Razor Sharp and highly polished blade is to follow on from Phase Two with either a 1000 or a 1200 grit Japanese Water Stones, which will further refine, partially polish and remove scratches from your knife blade that previous grit sizes create.

Phase Four to achieving a Razor Sharp excellence is to bring your knife blade edge to a near mirror and then a mirror finish; this is done on the 4000 grit, the 6000 grit, 8000 grit and the ultimate 10,000 grit Japanese Water Stones, which is helped along with the additional use of a Japanese Nagura Stone.

Phase Five, the final Phase, to achieving a Razor Sharp perfection is to is to Strop the knife edge with a good quality leather strop such as the Shark Designs - Field Razor Strop (Deluxe) or Hand Razor Strop. Stropping a cutting edge helps to further polish the edge and if done often enough constantly realigns any curling that might be taking place. There are two main types of strop; one is just a simple strop that has no abrasive properties whatsoever and is basically used to polish and realign the blades cutting edge as already mentioned, the second is what is known as a Honing Strop. The Honing Strop is a basic strop that has been impregnated with a honing compound such as White Jewellers Rouge or something like Tormec’s Honing Paste. Honing will abrade the blades cutting edge, all be it at a very low level, making it absolutely ideal for resetting a cutting edge that is just beginning to dull, back to a Razor sharp state, thereby prolonging the periods between re-sharpening.
